Children and adolescents who are having difficulty coping with stress often present with complaints of physical discomfort. Effective treatment approaches exist for many of these issues. Among high-conflict parents, however, children's medical issues can become another canvas for conflict, with parents focused more on blaming one another for the child's distress than on options for assisting the child. Professionals can be drawn into the conflict to such a degree that they overlook essential steps for addressing and managing these issues. The authors present a research-informed model for managing medical and psychophysiological issues amid parental conflict.  相似文献

Estimates of the incidence of victim gun use from the National CrimeVictimization Survey (NCVS) are consistently lower than are those fromother studies. To examine the divergence, we conducted a survey that gaugedthe impact of methodological differences between the NCVS and the otherstudies. For half of the sample, we asked questions from the NCVS, followedby questions from the other surveys. For the other half of the sample, wepresented the questions in the reverse order. We examined two hypotheses:(1) survey methods account for the divergent results, and (2) the questionscover unrelated activities. The results provided some support for the firsthypothesis, but respondents also reported many more defenses to thequestions from the other surveys than to the NCVS questions. Consistent withthe second hypothesis, this suggests that the NCVS and the other surveysmeasure responses to largely different provocations.  相似文献

The U.S. tax law equates the tax rate on dividends and long‐term capital gains on stock owned by U.S. citizens and residents. However, the taxation of these two types of rewards in the hands of foreign portfolio investors remains dramatically different from each other, with the capital gain being fully exempt. Several reasons support this article's proposal to no longer exempt these gains. Extending finance theory and prior normative tax research, this article argues that foreigners’ portfolio dividends and capital gains should be taxed in the same manner because they are economically equivalent and emanate from the same source. Three recent empirical developments also support repeal of the foreigner's exemption. First, there is now extensive use by U.S. corporations of stock repurchases—which are taxed to selling shareholders as capital gain—as a form of corporate payout that was in the past primarily accomplished through dividends. Second, foreign ownership of U.S. stocks has continued to increase, with an estimated one‐third of these stocks owned by foreigners. Third, the modern tax compliance environment—including aspects of the Foreign Account Tax Compliance Act that apply to foreigners—reduces past congressional and academic concerns about enforcing the taxation of foreigners’ portfolio gains.  相似文献

In their paper Beyond Procedural Justice, Bottoms and Tankebe specified two interrelated dimensions of legitimacy: audience legitimacy and self-legitimacy. Criminologists have given considerable attention to audience legitimacy, but police officers’ belief in their own legitimacy remains understudied. This paper extends Bottoms and Tankebe’s theory and reports findings on some of its key propositions, using survey data from a UK police force. Three key findings emerge. First, contrary to previous studies, feelings of recognition by supervisors and clientele did not predict self-legitimacy; self-legitimacy was found to depend on feelings of peer recognition and acceptance. Second, self-legitimacy predicted officers’ commitment to external procedural justice but not their moral orientations towards crime victims. Finally, perceived police effectiveness but not supervisor recognition – that is, internal procedural justice – was the key predictor both of external procedural justice and of normative orientations towards crime victims. The implications of these findings are discussed.  相似文献

Hot spots policing is popular, yet little is known about officer receptivity to the tactic and its impact on internal procedural justice, organizational commitment, and self-legitimacy. The nature of the tactic means that officers must relinquish their discretionary powers so that they can be directed to crime and disorder locations at specific times and for regimented durations. This loss of ‘spatiotemporal autonomy’ is exacerbated by technological tracking devices. We examined the receptivity of British officers to hot spots patrols, where the deployment was tracked with individual GPS trackers, compared to parallel patrols without hot spots policing or tracking. In contrast to the comparison group, officers in hot spots disliked the routinization of their shifts; regimented patrols were detrimental for internal procedural justice and organizational commitment. The ramifications of the introduction of GPS-enabled systems include certain tracking of officers and their compliance, such as a Taylorist time and motion study. While hot spots policing remains an effective tactic, questions about sustainability may be raised if officers’ expectations, attitudes and receptivity are not managed.  相似文献

This study seeks to provide a greater understanding of the factors that determine the perceived availability of alcohol and its role in predicting adolescents’ alcohol use. Participants were 151,703 7th–12th grade students (50% female) from a sample of 219 rural communities across the United States, with oversampling for predominantly Mexican-American and African-American communities. Multilevel analysis was used to estimate the perceived availability of alcohol as a function of physical and social availability measures and individual and community-level control variables. Physical availability was measured as the number of alcohol outlets in the community and whether beer and wine were sold in non-liquor stores. Social availability measured the availability of alcohol from social or family groups. Last month alcohol use was then estimated as a function of physical, social and perceived availabilities and control variables. Physical availability had little relationship to perceived availability or recent alcohol use while social availability was a strong predictor of both. Perceived availabilities at the individual and community levels were significant in predicting last month alcohol use. The findings suggest that altering both perceived and actual availability of alcohol can potentially have strong effects on the levels of adolescent alcohol use.  相似文献

This rulemaking changes the regulation of the listed chemical iodine under the chemical regulatory provisions of the Controlled Substances Act (CSA). The Drug Enforcement Administration (DEA) believes that this action is necessary to remove deficiencies in the existing regulatory controls, which have been exploited by drug traffickers who divert iodine (in the form of iodine crystals and iodine tincture) for the illicit production of methamphetamine in clandestine drug laboratories. This rulemaking moves iodine from List II to List I; reduces the iodine threshold from 0.4 kilograms to zero kilograms; adds import and export regulatory controls; and controls chemical mixtures containing greater than 2.2 percent iodine. This rulemaking establishes regulatory controls that will apply to iodine crystals and iodine chemical mixtures that contain greater than 2.2 percent iodine. This regulation therefore controls iodine crystals and strong iodine tinctures/solutions (e.g., 7 percent iodine) that do not have common household uses and instead have limited application in livestock, horses, and for disinfection of equipment. Household products such as 2 percent iodine tincture/solution and household disinfectants containing iodine complexes will not be adversely impacted by this regulation. Additionally, the final rule exempts transactions of up to one-fluid-ounce (30 ml) of Lugol's Solution. Persons handling regulated iodine materials are required to register with DEA, are subject to the import/export notification requirements of the CSA, and are required to maintain records of all regulated transactions involving iodine regardless of size.  相似文献
